4QF- Q IMPRO'VEMENTIN APPARATUS FOR MAKING SOLID CORES.

The Schedule xeferred'to in theso Letters Patent and making part of the same.

To all whom 'it may concern:

Be. it known that I, S. J. FEET, ofthe city, count-y, and State of New York, have invented a new and improved Machine for Making Solid Cores; and'I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had tothe accompanying drawing forming part of this specilcation, in which- Figure 1 represents a longitudinal vertical section of this invention.

Figure 2 is a transverse vertical section of the same.

Similal letters indicate corresponding parts.

This invention relates toa machine for making solid cores, which is coinposed of'astationary table, forming the support for the core-plate, and the guide for a rilsing and falling gate, which supports the templetp ate.

0n this templet-plate is laid the 4hopper-plate, through the funnel-shaped apertures of which the sand is introduced into the holes in the templet-plate,

`and the sand is rammed down with the required uniform degree of force by a series of rams or stamps secured to a common head or follower, which'i's depressed by a hand-lever or otherwise.

After the sand has been rammed down sufficiently tight, the hopper-plate is shoved ott' from the templetplate horizontally, thereby carrying otf thesurplus sand, and smoothing down the surface of the cores, and by rapping the templet-plate the cores contained therein are loosened, so that when the templct-plate is raised said cores are deposited upon the core-plate, which, together with t-he cores, can be easily removed.

1n the drawing, the letter A designates a frame made ofwood or any other suitable material.

This frame supports a platform or table,B, which is provided with a recess to receive the core-plate C, which is cast ot' type-metal, or made of lany other suitable material, andas thin as may be compatible with the required strength. y

Through the table B extend two standards D D, the bottom ends of which are connected by a strong inverted roofshaped bar, E, while their top ends form the supports for the templet-plate F, which is firmly secured to the same, and which is provided with a series of apertures or holes to correspond to the cores to be formed.

The inverted roof-shaped bar E is acted on by a cam, G, which is mounted on a shaft, H, extending transversely across the frame A, and being so arranged that it can be revolved either by hand, toot, or other power. By turning said shaft, the cam G bears against the bar E, and the templet-plate F- is raised from the table B.

On the templet-plate F is placed the, hopper-plate I, Awhich is cast of metal in a similar mold to the tempiet-plate,y and perforated by the same number of holes, being of the same shape as those in the templetplate, except that they are made a little bell-mouthed to receive the sand or other substance for the cores.

lVhcn each core-box and its hopper shall have re. cevcd its proper amount of sand, they are. all stamped or rammed by a gauged force by means of a series of rams or stamps, J, which are attached to acommon head, K, that' slides up and down ou guide-bars L, and is exposed to the action of springs a, whichhave a tendency to raise the same up to the posit-ion shown in the drawing From' said head extend rods b to levers c, which extend from a rock-shaft, d, so that by imparting to this rock-shaft an oscillating motion, the head is raised or lowered, and by depressing the head the several rams are brought into action, and the sand in thecoreboxes is compressed with the required force.

After the. sand has been compressed, the rams are raised and the hopper-plate'I is shoved ofi` from the templet-plate in a horizontal direct-ion, so that the surplus sand is carried olf, and the upper surface ot the cores is smoothed down.

The cores in the templet-plate are then liberated by a few raps, and by a gentle motion of the cam G the tcmplet-plate is raised, while the cores are deposited on the core-plate C, which being loose can be ea illy removed, and together with the cores introduced into a drying-kiln or oven, while another core-plate is put in its place, and the same process is repeated.

By these means the operation of making cores is simplified, so that it can be readily performed by children, and by changing the templet-plate, t-hel hopperplate and the rams of my machine'can be used for molding solid coresof any desired description.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

The rising and falling standard D D, in combination with the templet-plate F, table B, core-plate 6,*hopper-plate I, and stamps'J, all constructed substantially in the manner herein shown and described.

This specilication signed by me this 17th day of June, 1869. y
